WATER-HEATING APPLIANCE FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Dec. 22, 1914.

Application filed July 25, 1918. Serial No. 781,229.

To all whom it may concern:

lie it known that we, ALBERT MATTHEWS and ;\LI"R:'-1D lvlrnncn, both of the city of \Vinnipeg, in the Province of h'lanitoba, Canada, have invented certain new and useful Improvements in \Vater-Heating Appliances for Automobiles, of which the following is the specification.

The invention relates to a heating appliance attachable especially to automobiles and the object of the invention is to provide a device whereby the water customarily contained within the water jackets, radiator and connecting pipes of an automobile engine can be kept heated when the engine is idle thereby avoiding the possibility of the water freezing in these parts in countries where low temperatures are experienced.

With the above objects in view the in= vention consists essentially in a heater located in any suitable position on the auto-- mobile, the heater being supplied with a boiler, inlet and outlet pipes connecting the heater with the water cooling system of the engine, the parts being arranged and constructed as hereinafter more particularly described and later pointed out in the appended claims.

Figure 1 represents a side view of the front end of an automobile chassis showing our invention applied. Fig. 2 represents a plan view of the same. Fig. 3 represents an enlarged detailed vertical sectional View through the boiler. Fig. i represents an enlarged detailed horizontal sectional View through the boiler. Fig. 5 represents an enlarged detailed back view of the boiler casing removed.

lu the drawings like characters of reference indicate corresponding parts in each figure.

1 represents the frame of an automobile carrying as usual a radiator '2, a dash-board 3, foot boards -l and engine 5, the engine presenting in the present instance the cylinders 6, 7, 8 and 9.

10 represents a water lead pipe connected with the top of the radiator and communicating through branch pipes 11., 12, 13 and 14 with the customary water jackets of the several cylinders.

15 represents a return water pipe connected with the lower portion of the radiator and communicating with the various cylinder jackets through the branch pipes 16, 17, 18 and 19.

The above parts are all of ordinary coni struction and form no part of our invention.

In actual practice there is a circulation of water through the cylinder jackets and radiator and the lead and return pipes, this water being utilized to keep the cylinders from heating unduly when in use, the Water circulatlng being cooled in passage through the radiator.

In countries where cold weather is experienced considerable trouble is caused by the water actually freezing in the jackets lead and return pipes or the radiator when the engine has been left standing idle, this occurring particularly where one is making long stops and does not desire to leave the engine running. To overcome this difficulty we have provided the following attachment which is in reality a heater suitably connected so that a circulation of hot water canbe established through the jackets, lead and, return pipes and the radiator, that is through the water cooling system of the engine when the engine is out of commission.

The heater 20 in the present instance is connected to the dash-board 3 in any suitable manner and it comprises a tubular water containing boiler 21 and a source of heat the source of heat being indicated in the present instance by a gas burner 22* the gas burner being positioned directly beneath the boiler. The burner is carried at the upper end of a gas pi e 23 which passes downwardly to the foot oards 4 where it is connected with a gas tank 24. We do not consider it necessary to supply a. special gas tank as a great many of the automobiles now on the market are fitted with gas tanks, these being part of the lighting system.

represents a valve located within the length of pipe 23 controlling the flow of gas through the burner.

26 is an outlet pipe passing from the top of the boiler to the radiator, this ipe entering the radiator at a point be ow the entrance of the pipe 10 to the radiator. It

is to be noticed that this pipe is actually in a lower horizontal plane than the pipe 10.

27 is a branch pipe connectin the pipes 26 and 10 more or less centrally of their length.

28 is an inlet pipe opening to the bottom of the boiler and communicating with the bottom of theradiator. The boiler is inclosed within an asbestos lined"cas-ing 29 which has the lowerend thereof extending downwardly to protect the burner. The

casing is in the form of a vertically split cylinder having the two sections hinged at structed so that the casing can be readily rep This is done moved to inspect the boiler.

by lifting ofi? the top and undoing the releasable lock.

With the above apparatus installed on an automobile it is only necessary for one to turn the valve 25 and then light the gas escaping through the b'urner,-the resultant flame heating the water in the boiler and so causing a circulation. of heated water through the cylinder jackets, pipes and radiator and thereby. preventing the possi- 'bility of burst. pipes jackets or radiator through freezing as commonly occurs.

.In actual practice we find that the Water flows from the boiler through the pipe 26 till it reaches the pipe 27 where it passes upwardly and branches into the pipe 10 flowing in opposite directions in said pipe at the point of entrance. From the pipe 10 it is distributed to the various cylinder jackets and also the radiator the flow to the jackets being through the branch pipes 11, 12, 13 and 14. The water passing into the jackets is released through the pipes 16, 17', 18 and 1 9 and collected by the pipe 15 which passes it directly to the bottom of the radiator the pipe 28 then returning the water to the bottom of the boiler thus completing the circulation. We find that in actual practice there is no flow through that portion of the'pipe 26 appearing between the branch pipe and the radiator when the appliance is in use. This is explained by the fact that the pipe 26 enters the radiator below the water level in said radiator while the pipe 10 ,entersit above. the Water level.

Thepipe connections above described provide a very even distribution and flow of water through the jackets and radiator, the

circulation being established through all of these parts very quickly after the burner has been lighted. We do not however wish to be restricted to the precise form of heater used as various other forms could be readily suggested and applied to equal. advantage nor to the particular way in which the inlet and outlet pipes are connected up with :of the engine, of a boiler mounted in any suitable location on the automobile, means for applying heat to the boiler, an outlet pipe passing from the top of the boilerto the top of the radiator, a branch pipe con' necting the outlet pipe with the lead pipe aforesaid and an inlet pipe connecting the bottom of the radiator with the bottom of the boiler, as'and for the purpose specified;
